EPSI Updates

Why do my EPSI graphs look different?

We have made two updates to the EPSI: 1) The norms, or benchmarks, at each month of age have been revised based on scores from a larger sample of children (N = 2,719), and 2) the EPSI total score is now a weighted total score. The EPSI Weighted Total score is calculated by summing Looks + Explores + Functions(x2) + Solutions(x3). Like the ECI Weighted Total score, the EPSI Weighted Total score gives children more credit for more advanced problem solving skills.

See the sample graphs below for explanations of specific changes:
